Similar thing happened with my old school, i moved to a much smaller school, for most of my GFPT I had the same instructor, and when I had a different one they showed interest and saw logic in what i was taught by other instructors as opposed to saying I was wrong.
For the PPL navs up to solo (excluding solo recommendation) I had the same instructor.
Means less hassling around (and probably less wasting money) due to instructors wanting to spend more time seeing what else you have been taught differently as opposed to getting on and doing the lesson?
